HAAS 30 Amp 32-5550E Servo Amplifier
 |
The HAAS 32‑5550E (93‑32‑5550E) is a 30 A brushless servo amplifier that drives the motor from the CNC controller. Common failures include power‑supply ripple or voltage spikes damaging the internal MOSFET array, degraded electrolytic capacitors on the high‑voltage side, and thermal overload causing the built‑in over‑current protection to trip; older units may also suffer from PCB corrosion or broken trace connections after prolonged use. First‑check diagnostics: verify that the input 48 VDC supply is within spec and free of noise, inspect the amplifier’s heat sink and airflow for overheating, and review any fault codes displayed on the controller panel or in the CNC log for over‑current or short‑circuit indications.[oss-gpt-20b] |
